WHEN you get a power adder, get a real tire if you are actually worried about traction(hoosier, m&h, M/T). wider will not instantly equal more traction, you need a better compound tire. throw a real drag radial on those foundry's and see how she hooks at any power level
I like the stock styling much better. (sorry don't like the styling of the SVE's)
The 20" stock wheels kind of look like the Boss Laguna Seca wheels, thus going with your stripe look.
Obviously, our cars need wider rear tires for high performance driving. But if you're putting a lot of miles on your car as a daily driver and/or driving it in the winter you might want to just keep the stock wheels on. Then you can use the other wheels for track days.
5L equals 302 cubic inch...it isn't exactly 5L anyways. If you like it roll with it. I am not a huge black wheel fan but the car screams for them. Between the two go back to original.
